CONNECTION SYSTEM Russian patent published in 2021 - IPC B05B11/00 B65D41/17 

FIELD: spraying devices.

SUBSTANCE: connection system of a trigger spraying head and container (4) of a spraying device contains neck (8) of container (4) having round cylindrical outer surface, skirt (32) of the spraying head, consisting of a skirt wall having a free skirt edge. On the outer surface of the neck, there are a control area having a control passage or a control guide for engagement with latching; an area of the first retainer adjacent laterally in the circumferential direction to the specified control area and containing a guide of the first retainer, having an input passage of the first retainer, and a sliding platform of the first retainer, having an output passage of the first retainer; a shelf area adjacent laterally in the circumferential direction to the specified area of the first retainer and containing an upper shelf; an area of the second retainer adjacent laterally in the circumferential direction to the specified shelf area and containing a guide of the second retainer, having an input passage of the second retainer, and a sliding platform of the second retainer, having an output passage of the second retainer. The skirt contains a rigid control tooth or a flexible control tongue; the first flexible tongue and the rigid tooth of the first tongue, located next to the first tongue between the specified first tongue and the edge of the skirt; the second flexible tongue and the rigid tooth of the second tongue, located next to the second tongue between the specified second tongue and the edge of the skirt. Exclusively in one predetermined angular position between neck (8) and skirt (32), the control tooth is aligned with the control passage or the control tongue is aligned with the control guide, axial engagement with latching between the skirt and the neck is possible (aligned engagement arrangement).

EFFECT: ensuring that the neck of the container and the skirt of the trigger spraying head engage with each other exclusively in the corresponding predetermined angular position, in which an axial connection with latching between the skirt and the neck is possible.
